Actually... Unless the docs are lying to me... empty() checks the contents of the value, and does something quite different based on the value found. isset() just plain checks in the hash table[s] if the variable has been assigned, and that's it. Plus, the meaning of empty() changed in some a way with "0" between versions 3 and 4, and then again with respect to objects with no properties between 4 and 5. isset() has never changed its meaning out from under me. :-) So, while the guts of the function may be the same in source, there's got to be some kind of flag or something going on for empty() to be checking all those values, no??? -- Like Music? http://l-i-e.com/artists.htm -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
